Answer:
$1,500
Step-by-step explanation:
A 2.5% increase in the $60,000 average family income would be required:
0.025 × $60,000 = $1,500
Your annual income would have to increase by $1,500.
Answer:
y = -2/5x + 3
Step-by-step explanation:
Start with your given:
2x + 5y = 15
Isolate y:
5y = -2x + 15
Divide 5 on both sides:
y = -2/5x + 3
Hope that helped. Hang in there! :)
Sample size, n = 75
Point estimate, p = 52/75 = 0.693
Z at 99.7% confidence interval ≈ 2.96
Population mean interval = p+/- Z*Sqrt [p(1-p)/n]
Substituting;
Population mean interval = 0.693 +/- 2.96*Sqrt [0.693(1-0.693)/75] = 0.693+/-0.158 = (0.535,0.851) or (53.5%,85.1%)
Answer:
Multiply each side by −5, add 25 to each side
Step-by-step explanation:
-1/5(x-25) = 7
Multiply each side by -5/1 to clear the fraction
-5/1* -1/5(x-25) = 7*-5/1
x-25 = -35
Then add 25 to each side
x-25+25 = -35+25
x = -10
Answer:
As n tends to positive infinity, we have that,
